cmruncl(1m)cmruncl(1m)NAMEcmruncl - run a high availability cluster
SYNOPSIScmruncl [-f] [-v] [-n node_name...] [-t | -w none]
DESCRIPTIONcmruncl causes all nodes in a configured cluster or all nodes specified
to start their cluster daemons and form a new cluster.
To start a cluster, a user must either be superuser(UID=0), or have an
access policy of FULL_ADMIN allowed in the cluster configuration file.
See access policy in cmquerycl (1m).
This command should only be run when the cluster is not active on any
of the configured nodes. This command verifies the network configura‐
tion before causing the nodes to start their cluster daemons. If a
cluster is already running on a subset of the nodes, the cmrunnode com‐
mand should be used to start the remaining nodes and force them to join
the existing cluster.
If node_name is not specified, the cluster daemons will be started on
all the nodes in the cluster. All nodes in the cluster must be avail‐
able for the cluster to start unless a subset of nodes is specified.
cmruncl supports the following options:
-f Force cluster startup without warning message and con‐
tinuation prompt that are printed with the -n option.
-v Verbose output will be displayed.
-t Test only. Provide an assessment of the package place‐
ment without affecting the current state of the nodes
or packages. The -w option is not required with the -t
option as -t does not validate network connectivity,
but assumes that all the nodes can meet any external
dependencies such as EMS resources, package subnets,
Start the cluster daemon on the specified subset of
-w none By default network probing is performed to check that
the network connectivity is the same as when the clus‐
ter was configured. Any anomalies are reported before
the cluster daemons are started. The -w none option
disables this probing. The option should only be used
if this network configuration is known to be correct
from a recent check.
cmruncl returns the following value:
0 Successful completion.
1 Command failed.
Run the cluster daemon:
Run the cluster daemons on node1 and node2:
cmruncl-n node1 -n node2
